game.clowns.paint

The greasepaint, generated. No clown's face in this game is a painted image: each one is drawn here from a description, into a base-colour / normal / roughness set that its material binds.

Exports

• Paint.head(spec) -> base, normal, roughnessMetallic, buffer — a face. The head texture is a cylindrical unwrap with the FACE at u = 0.5 and v running up the head's own lathe profile by arc length, so every feature in the spec is written in centimetres of real face: mouthY, mouthHalf, eyeSep, browY, cheekX and the rest. mouthLift lifts both corners of the smile and mouthSkew tilts the whole line, so one corner rides higher than the other. spec.profile is the head profile the figure was lathed from and spec.radius its widest radius. Optional muzzle and eyePatch lay white ground under the red, which is what separates an Auguste from a whiteface; optional tear paints a stripe straight down from the socket.
• Paint.cloth(spec) -> base, normal, roughnessMetallic, buffer — a bolt of cloth. spec.pattern is "diamond" | "stripe" | "plain"; the weave, the wear and the grime are always there. Woven neutral so a material's own base_color dyes it.
• Paint.mapping(profile) -> toV, toY — the height/v conversions a caller needs to place something on a head by where it sits in metres.
• Paint.at(buffer, w, h, u, v) -> r, g, b — what the generator put at one point, straight out of the buffer, so a face that looks wrong on screen can be told from a face that was drawn wrong.

Notes

• A face costs a second or two of pure Luau. Pass spec.chunkRows to spend it a band at a time and hand the frame back between bands; game.clowns.Roster does that so a spawn never freezes the game.
